Q1.a body hanging from a spring streches it by 1cm at
theearths surface. how much will the same body stretch the spring
at aplace 1600km above the earth's surface?
radius of earth=6400km.
q2.an earths satellite makes a circle around the earth in
90minutes. caculate the height of the satellite above the
earth'ssurface. given radius of the earth is 6400km and
g = 980cm/s2.

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

positive

step-by-step explanation:

the quadrant is facing upwards

a

step-by-step explanation:

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
